This 1 to 8-stop, 40.5mm Variable Neutral Density Filter from Raywowo is designed to reduce exposure while maintaining neutral color tone. Increasing neutral density offers finer control in available shutter speeds or aperture settings for both still and video applications.
This premium-grade filter is constructed from HD Japanese AGC optical glass. It features 20 layers of antireflective multicoating to reduce reflections and glare, enhancing contrast and clarity in both still photos and video. The coating also features water resistance, anti-fouling, fog prevention, antistatic, UV protection, scratch resistance, and easy fingerprint cleaning, providing comprehensive protection for the lens it is mounted on. The integrated aluminum frame provides a filter thickness of only 0.23", achieving an extreme ultrathin profile to minimize the possibility of vignetting.
